Charge control method of rechargeable battery and portable computer

Abstract

The invention provides a charge control method of a rechargeable battery and a portable computer. The charge control method comprises the following steps: acquiring charge current control parameters of the rechargeable battery; modifying a first charge current of the charge current of the rechargeable battery into a second charge current, wherein the second charge current is less than the first charge current; and using the second charge current to charge the rechargeable battery. The charge control method is used to change the existing mode that the battery is charged by the maximal current, thus improving the service life of the rechargeable battery.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a charging control method of a rechargeable battery and a portable computer. Background technique [0002] At present, for some users, notebook computers are powered by rechargeable batteries every day. Therefore, rechargeable batteries may need to be charged and discharged once a day, and the rechargeable batteries can be used up to 300 times a year, or even more. [0003] It is well known that the number of cycles of rechargeable batteries has a certain limit, and when the number of cycles exceeds a threshold (such as 300 times), its usable capacity will rapidly decay, such as decaying to 70% of the initial capacity or even lower. [0004] Once the usable capacity of the rechargeable battery decays, the rechargeable battery cannot meet the user's battery usage time requirements, and the battery cannot continue to be used, so the battery can only be replaced.

[0003] It is well known that the number of cycles of rechargeable batteries has a certain limit. When the number of cycles exceeds a threshold (such as 300 times), its usable capacity will rapidly decay, such as decaying to 70% of the initial capacity or even lower.

[0004] Once the usable capacity of the rechargeable battery decays, the rechargeable battery cannot meet the user's battery usage time requirements, and the battery cannot continue to be used, so the battery can only be replaced

[0005] In the process of realizing the embodiment of the present invention, the inventor found that charging the rechargeable battery according to the existing constant voltage and constant current method will reduce the service life of the rechargeable battery
